【Abstract】 A nondestructive testing technique for evaluating the quality of building components is presented. It employs a simple, portable instrument to measure the time difference for the longitudinal vibration wave propagation in the component directly. The results are analyzed and judged by a microprocessor. The device is suitable for general engineering use.更多还原
